Problems solved by technology

As a naturally growing organic material, under the influence of external conditions such as solar radiation, rainwater leaching, decaying bacteria and other surrounding environmental factors, the wood material is extremely prone to deterioration—the surface of the wood becomes rough and dull, the quality of the wood decreases, and the surface cracking, eventually leading to scrap

Abstract

The invention relates to the technical field of wooden product processing and manufacturing, and discloses a treatment method for improving the water resistance and the light aging resistance of wooden products. After wood is treated with a prepared metallic nickel organic solution, metallic nickel can permeate into wood cells, and therefore the mechanical property of the wooden products is improved; a hydrophobic agent and hydroxide radicals on the surface of nano-titanium dioxide sol generate a chemical reaction, alkane long chains are successfully grafted on the surface of the wood, and therefore the wood achieves the good hydrophobic property; for second-stage convex-concave structures on the surface of the wood, the convex-concave structures are modified with hydrophobic substances, and therefore the hydrophilcity of the wood surface is changed into hydrophobicity; meanwhile, the light aging resistance of the wood is improved through the good ultraviolet absorption capability of the inorganic nano-material, and then the functional wooden products with the hydrophobicity and the ultraviolet protective property are obtained.

Description

technical field [0001] The invention belongs to the technical field of wood product processing and manufacture, and in particular relates to a treatment method for improving wood product water and photoaging resistance. Background technique [0002] As a natural resource, wood has the characteristics of natural degradation, regeneration and good environmental coordination. With the continuous development of society and the improvement of people's living standards and environmental protection awareness, people turn their attention to natural and non-hazardous wood products. As a natural, environmentally friendly, renewable and beautifully textured biomass material, wood is loved by people for its excellent environmental characteristics and has been widely used in construction, furniture, decoration and other fields. As a naturally growing organic material, under the influence of external conditions such as solar radiation, rainwater leaching, decaying bacteria and other surr...
